Corporation is an FPS developed by Dimension Creative Designs and published by Core Design. It was released in 1990 for the Amiga and Atari ST computers, in 1991 for MS-DOS, and 1992 for the Sega Mega Drive / Genesis console (retitled Cyber-Cop in North America).
The Universal Cybernetics Corporation has been illegally producing genetically engineered mutants. Now the creatures are on the loose and wreaking havoc. You are a special government agent, trying to infiltrate their London facilities to expose their crimes.
This game may look simplistic now due to its flat polygon walls, but its gameplay was tremendously advanced for the time. It combined a 3D first person perspective with elements of roleplaying, stealth, and hacking — many years before System Shock and Deus Ex.
